CREAM-COOLER.

Application filed February 15, 1917, Serial No. 148,797.

1 State of Minnesota, have invented certain new and useful Improvements in Cream- Coolers, of which the following is a specification.

My invention relates to improvements in cream coolers, its object being to provide an improved construction of cream cooler in which preliminary cooling cans, together with additional storage cans are preferably employed and in which the cream in the preliminary cooling cans is cooled through the medium of running water in the quickest possible and most efficacious manner. My invention further consists in the features of construction and combination hereinafter more particularly described and claimed.

In the accompanying drawings forming part of this specification,

Figure 1 is a perspective view of a cream cooler embodying my features of invention and shown partly broken away and with a portion of the parts removed.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a vertical section through one side wall of the cooling cabinet showing an adjacent storage can partly broken away.

Fig. 4 is a detail of the hanger for the storage cans.

Fig. 5 is a detail of the locking device for the preliminary cooling cans.

In the drawings A represents a tank within which are adapted to be arranged the cream containers B, and the storage cans C, the containers B being designed for the preliminary cooling of the cream and the can C for the storing of the cream after it is cooled in the containers B. The tank is formed with water inlet conduit 2 and an outlet conduit 3, the inlet conduit 2 opening into the top of the tank at one end and the outlet conduit leading from the outward end of the tank above the point where it is desired to maintain a level of the water within the tank.

Vithin one end of the tank is permanentlysupported one or more open top. cylindrical chambers 4, the said chambers-rat their bottoms opening into a hollow base 5, and the said base communicating by a conduit 6 with the inle pipe 2. A grating 7 is supported on the bottom of each chamber 4 above the base. Adapted to be positioned within the cham- Specification of Letters Patent.

bers 4 upon the gratings are cream containers B provided with suitable covers 9. For

the purpose of supporting the chambers 4 1n posltion and furnlshlng anchoring means for the containers B I preferably provide cross bars 10 connecting the side walls with the tank alongside the, chambers 4, said cross bars being formed with outwardly projecting V studs 11, and the containers B supporting upon their sides loops 12 adapted to hook over the studs 11, as shown best in Fig. 5.

The loops 12 are, as shown fulcrumed in brackets 13 secured upon the sides of the containers so that when the containers are placed within the chambers 4-, the fasteners may be sprung into or out of locking'engagement with the studs by pressing the outer ends of the fasteners toward the containers, as indicated by the dotted line in Fig.2.

For the purpose of supporting the relatively large can C within the tank and prevent it from being moved by the water, I provide upwardly projecting flanges 15 secured upon the floor of the tank to form seats for said cans. Secured to the side walls of the tank are vertical ribs 16 formed with a plurality of downwardly projecting slots 17. A hook 18 is employed to fit at its lower end into one of the slotted openings 17, as shown in Fig. 3, with its upper curved end hooked over the adjacent handle 19 of the storage'can. WVhen not in use the hook 18 is adapted to be suspended from the rib 17 by the hinge in the upwardly projecting slots 20 of the ribs 16, as illustrated in Fig. 4'.

In use the'cream is first placed in the relatively small containers B. The water in passing through the tank passes upwardly in a thin stream between the containers B and the side walls of the chambers 4, thence pouring over the top of the chambers 4 into the tank. The water within the tank surrounds the storage cans and is kept at the desired level by the outlet conduit 3. A thin stream of cold water passing from underneath the containers B upwardly around the sides thereof results in a particularly rapid cooling action upon the cream. When the cream is cooled it is poured into the larger storage cans C where it is kept in the proper condition by the water surrounding the storage cans.

By means of my features of construction I secure a very rapid cooling of the cream in the comparatively small containers B,

and also keep the cream stored in the larger cans G. in a proper cool condition. The cream placed in the storage can C being already cooled by the rapid cooling action of the small container arrangement, is easily kept cool by the mere submersion of the storage cans in a body of water within the tank. A suitable cover 21 may be employed for the tank.

I claim v 1. A cream cooler of the class described comprising a tank, an open topped chamber supported within said tank, a hollow base for said chamber, an inlet conduit connecting with said base, a can supported within said chamber and separated from the sides thereof, and an outlet conduit for said tank positioned above the bottom thereof.

2. A cream cooler of the class described comprising a tank, an open topped chamber supported in said tank, a hollow base for said chamber, an inlet conduit for said base, a can removably supported within said chamber upon said base, and anoutlet conduit for said tank positioned above the bottom thereof and beneath the level of the top of the chamber.

*8. A cream cooler comprising atank having an outlet at one end, a storage can arran ed in the specified end portion of the tank, an open topped chamber supported in the opposite end portion of the tank, and a water inlet for the tank opening thereinto through the chamber, and connected to the bottom of the chamber whereby the inflowing water must of necessity pass through the entire length of the chamber prior to flowing outinto the tank for cooling the storage can.

4. In a cream cooler of the class described, a tank, an open topped chamber supported in said tank and a hollow base for said chamber communicating therewith, an inlet conduit communicating with said base, a cream can positioned within said chamber and spaced therefrom, a support for said can adjacent to the bottom of said chamber, and an outlet conduit for said tank positioned above the bottom thereof.

5. In a cream cooler of the class described, a tank, an open topped chamber supported therein and from which the cooling water overflows thereinto, an inlet conduit opening into the bottom of said chamber, andra can supported in said chamber, and spaced therefrom, an outlet conduit for said tank.

6. A cream cooler of the class described comprising a tank, an open topped chamber supported therein, an inlet conduit opening into the bottom of said chamber, a can sup- 7. A cream cooler of the class described comprising a tank, an open topped chamber supported therein, an inlet conduit opening into the bottom of said chamber, a can supported in said chamber and spaced therefrom, a hand actuatable locking means carried by the can for normally securing said can within said chamber, and an outlet conduit for said tank positioned above the bottom thereof.

8. A cream cooler comprising a tank, a vertical conduit therein having a bottom T-shaped extension, spaced vertically disposed chambers mounted on the T-shaped extension, the latter opening into the bottoms of the chambers, means bracing the upper ends of the chambers from the walls of the tank, containers arranged within the chambers and spaced from the walls thereof for providing circulating passages about the contamers, and means for securing the containers to the brace means.

9. A cream cooler including a horizontal conduit, a vertical chamber communicating therewith and having a grate-like bottom, a container of smaller diameter arranged therein to define a circulating assage therebetween, and means securing the container in the chamber.

10. A cream cooler comprising a tank having an outlet, an upright chamber disposed within the tank, closed at its bottom and opened at its top for overflowing into the tank, and an inlet for thetank connected to the bottomof the chamber for passing a cooling'fiuid initially therethrough preliminary to entering the tank.

11. A cream cooler comprising a tank, a receptacle disposed therein, and means for securing the receptacle in the tank consisting of a vertical rib-like member secured to the tank and formed with a series of inclined slots, and a hook-member selectively engageable in the slots and adapted for hooking over a pro ecting part of the receptacle,

which may vary in size, for holding the same within the tank.

In testimony whereof I atfix my signature in presence of two witnesses.
